Aging pope uses wheeled platform in St. Peter's

Pope Benedict XVI began using a wheeled platform Sunday to navigate the long aisle of St. Peter's Basilica, adopting the device employed by his ailing predecessor to reduce fatigue.

Benedict's predecessor, Pope John Paul II, started using the gold-colored platform in his final years of the papacy, when Parkinson's disease made it increasingly difficult for him to walk steadily or without fatigue.
